Duct heater connecting rod

The fan connected to the air inlet introduces the wind into the air duct heater through the air inlet, the wind introduced into the casing is sprayed onto the spoiler, and the wind is evenly distributed to the air distribution plate through the spoiler, so Pass the air distribution plate to the heating pipe, and the air distribution plate is provided with several air inlet holes, the air inlet hole diameter is between 10mm-16mm, so as to ensure the stable flow field velocity of the air volume introduced into the heating pipe through the air inlet hole Sex accelerated.
